Answer:
The correct option is ₋₁⁰β
Step-by-step explanation:
Beta radiation or beta emission is a type of nuclear radiation that emits beta particles which are either electrons or positrons (electrons that are positively charged). Beta particles are represented with "β". When the beta particle is an electron, it is denoted as ₋₁⁰β and the reaction is said to be a beta minus decay. But when the beta particle emitted is a positron, it is denoted as ₊₁⁰β and the reaction is said to be a beta plus decay.
Example of a beta minus decay is
¹⁴₆C ⇒ ¹⁴₇N + ₋₁⁰β
Example of a beta positive decay is
¹⁸₉F ⇒ ¹⁸₈O + ₊₁⁰β
